CoatingsPro article: How to Specify a Slip-Resistant Floor Coating

An article in the March 2020 edition of CoatingsPro™ Magazine details how to specify an anti-slip floor coating, specifically a transparent one. (A printable version of the article is also available.) After establishing a reliable method to determine wet slip resistance, the article discusses initial slip resistance safety criteria; durability testing of the coating’s slip […]

BOT-3000E Manufacturer Advises Against Using ANSI/NFSI B101.3 and B101.1 to Assess Floor Slip Resistance

The manufacturer of the BOT-3000E digital tribometer is Regan Scientific Instruments of Carrollton (Dallas), Texas. Recently we asked Regan for an update on ANSI B101.3, “Test Method for Measuring Wet DCOF of Common Hard-Surface Floor Materials,” approved January 18, 2012, and ANSI/NFSI B101.1. We received a reply from Peter Ermish, President. Here’s part of his […]

U.S. Senate Bipartisan Report: Falls Kill an American Senior Every 19 minutes

Lest we think that the U.S. Senate is capable only of partisan wrangling, the bipartisan Senate Aging Committee has published a report on falls prevention in efforts to protect those 65 and over from injury and premature death. Every 11 seconds an older American is treated in an emergency room for a fall. Every 19 […]

Maximum Coefficient of Friction is not Limited to 1.00

It’s sometimes assumed that coefficient of friction (COF) has a maximum theoretical and practical  value of 1.00. This isn’t true; there is no maximum. It is true that values exceeding 1.00 are so slip-resistant that their actual value is often of little interest. Some COF measuring instruments, such as BOT-3000E and English XL, are not […]

What Should the Slip Resistance of a Bathtub Be?

Bathtubs, in hotels or homes, are in areas where slip accidents can be very serious or fatal because there are hard objects in close proximity that can be easily struck by the head after a slip — the side of the tub, the faucet, toilets and sinks. Bare feet are soft and essentially treadless, and […]

Slip Resistance Safety for Industrial and Commercial Areas

Minimum wet slip resistance values (as wet Pendulum Test Values) for safety in many publicly accessible areas are listed elsewhere on this blog. But what about industrial areas used for very slippery operations like meat or fish processing, making mayonnaise or refining cooking oils, and for aircraft repair hangars? Guidance for these, recommended since 1999, […]

Germany’s DIN 51130 Slip Test: What’s it Good For?

In Europe a slip resistance test for flooring is prescribed by German Institute for Normalization (DIN) standard DIN 51130. A person wearing industrial-type treaded shoes walks, facing downslope, on a variable-angle ramp which has the flooring to be tested on it. The flooring is coated with motor oil. The walker (without holding the handrails) adjusts […]

SparkleTuff Outdoors on Level Surface and Stairs: 30-second video

The video below shows an outdoor level surface and stairs at a large mall, coated with transparent SparkleTuff™ Anti-Slip. A pedestrian walks down the stairs, which are partially wet from the previous day’s rain. With a material cost of about a dollar a square foot, SparkleTuff™ has excellent wet slip resistance by all respected test […]

Proven Standard Dynamic Friction (DCOF) Test Instrument for $1980!

The SlipAlert dynamic coefficient of friction tester has been in wide use for many years but now is offered by Safety Direct America for a limited time at close to half of its previous price! A roller-coaster type of dynamic floor slip tester, SlipAlert’s friction measurement was modeled after the physics of the pendulum DCOF […]

Many Polished Concrete Floors are Slippery when Wet

Can polished concrete floors be slippery when wet? Several web sites say yes, but others (mostly polished concrete vendors) say no, it only looks that way. A study of polished concrete published by the American Society of Concrete Contractors (ASCC) in Concrete International shows wet dynamic coefficients of friction (DCOF) as measured by ANSI A137.1 […]
